Brian,

Have a look at package aod on CRAN, and more specifically the functions "icc", "donner" and "raoscott".

More specifically, I am trying to determine the amount of clustering in a data set - that is, whether certain treatment programs tend to work with more or less severe clients. The outcome variable is dichotomous (low severity / high severity) and the grouping variable is the treatment program. Any suggestions for some R code or the appropriate R package would be greatly appreciated.
